I would be very appreciative if you were willing to do the work, and I know
others would be too. These kinds of cleanups may seem small individually, but
they make a _very_ real difference when we're looking kernel-wide at how
possible these struct page changes may be - and even if they don't happen, it
really helps understandability of the code if we can move towards a single
struct field always being used for a single purpose in our core data types.
